Pressure grinding type gravel making machine

Abstract

The invention discloses a grinding disc type gravel making machine. The machine includes a base. An adjusting oil cylinder, a deceleration motor assembly and a bracket are mounted on the base. A shelland at least one mounting seat are mounted on the bracket. The top of the shell is provided with a charging port, the bottom is provided with a discharging port, the side is provided with at least onopening, and the inside is provided with a grinding disc. The central axis of the grinding disc is perpendicular to the base. The deceleration motor assembly drives the grinding disc to rotate aroundthe central axis. A rotating arm is rotatably mounted on the mounting seat. A rotation axis of the rotating arm is parallel to the base. One end of the rotating arm is pivoted to a push rod of the adjusting oil cylinder, and the other end is provided with a roll shaft. The end of the roll shaft extends through the corresponding opening into the shell and is rotatably provided with a pressure roller at the end. A plurality of grinding disc filler blocks are arranged on the disc surface of the grinding disc. A plurality of pressure roller filler blocks are arranged on the roller surface of thepressure roller. The grinding disc type gravel making machine improves the quality of gravel and controls particle morphology and particle gradation of finished gravel. The equipment stably runs without obvious vibration, which greatly reduces running noise and production cost.

Description

technical field [0001] The invention belongs to the technical field of mining machinery and equipment, and in particular relates to a disc-type sand making machine. Background technique [0002] Sand making machines can use mechanical means to crush stones into small-sized gravel, and can be divided into many types according to different sand-making methods. [0003] Such as impact sand making machine and disc sand making machine. The former uses a high-speed rotating catapult to quickly throw the stones around, and under the impact with the lining block on the inner wall of the crushing chamber, it becomes smaller crushed stones, and then the crushed stones collide with the newly thrown stones to become smaller crushed stones. Smaller particles, after several repetitions to obtain gravel that meets the requirements, this sand making machine has a large processing capacity per ton, but due to a large number of collisions between the sand and gravel, its working noise is rel...

AI Technical Summary

Problems solved by technology

The defect of this kind of grinding disc sand making machine is that the gap between the pressing roller and the grinding disc cannot be adjusted, so that it is impossible to produce gravel with different particle sizes.
